Using the Bus Blaster to program Lattice CPLDs
One day when playing with the CPLD board I accidentally shorted out two pins on the on-board FT2232 and – unfortunately – the magic smoke escaped! It was very clear that the FT2232 failed because it got very warm when plugging in the USB cable. Luckily the dev kit includes a 0.1″ header landing to connect an external JTAG probe.
Wanting to get a Dangerous Prototypes Bus Blaster JTAG programmer anyway, this was the perfect excuse.
The Bus Blaster is a high-speed JTAG debugger for ARM processors, FPGAs, CPLDs, flash, and more. You can get a Bus Blaster v3 for $34.95 at Seeed.This entry was posted in Bus Blaster, CPLD and tagged Lattice, MachXO2280C, UrJTAG.
